X indicates that a measurement
was not possible due to poor data quality or was not made for highly oblique
impacts. NA indicates not applicable for impacts with no measureable ejecta.
(M) indicates the speed of the ejecta rim in the mirror. (C) indicates the
speed of the ejecta “cusp”.  Target
codes: S = quartz sand, L = JSC-1 lunar regolith simulant, M = JSC-Mars-1
martian regolith simulant, M500 = JSC-Mars-1, sieved to remove all particles
smaller than 500 mm.
See text for details. Ejecta mass codes (M1, M2, M3) are defined in the text.
